Doctors may one day be able to peek into your future stroke risk by looking at a picture of your eyes.

In a new study, patients with damaged blood vessels and mild eye blood pressure on pictures of their retina were 35 percent more likely to suffer a stroke. Those with moderate to severe eye blood pressure were 137 percent more likely to have a stroke.

Scientists need to do more research to confirm the link between eye vessels and stroke risk. But it’s good to adopt habits that reduce your blood pressure and improve your blood vessels.
